I work full time, but I work about 15 minutes from home so I am able to come home every day for lunch to take Anouk for a walk. When I'm at work, she is crated ( I hope to eventually not have to crate her, but we will see). I noticed this morning that she seems to be chewing the hair off of her her wrists/ankles (bone joint above the foot, front legs). Could this be a boredom thing? Or is it possible something else?

There could be any number of possibilities.
It could be some sort of parasite. Ticks, fleas, mange, ringworm, etc cause irritation and the dog chews or scratches excessively which causes fur/hair loss.
A trip to the vet may be worth your while just to rule out any of those sort of issues.

Boredom may be an issue. What you are doing with your dog for crating is perfectly fine and normal. Many people leave their dog in the crate longer than that. But does she have things to do in the crate? Toys? A blanket to cuddle with? Things to chew on? Do you rotate the toys? I find having a wide variety of toys, and swapping them around on a daily basis helps with boredom as they are constantly having new experiences instead of the same old thing every day.

It could also just be chewing/teething. Dogs are heavy chewers, and in my experience, huskies chew more than most breeds. My dog has eaten entire 2x4 boards, the siding off the house, etc...it's nuts. He gets adequate and regular exercise. He has plenty of toys and chews. He has a friend to hang out with. But he straight up eats everything he can get his grubby little mouth on...even metal fencing. He's teething, he has a strong urge to chew. It's a phase. However, if the dog doesn't have anything to chew, and is confined, she may resort to chewing on himself to relieve the urges.

Does he have enough room in the crate? Can she move around a little, can she stand up, can she turn around? If he was too confined to interact with stuff, she may be stuck just sitting and chewing.

Last but not least, have you noticed that the behavior is worse at any one time than another? Trains of thought I'm having... Do you walk her before work also? Maybe she just has a lot of pent up energy waiting for that noon walk and this is her way to vent that. Does it happen more in the afternoon? Maybe you walk her in the morning but he has time to calm down before being crated...but at noon you are pressed for time, you get yourself food, feed her, give her a quick walk and then back to the crate while bubbling with energy. Maybe exercising first, then having some time to relax before the crate would help.

Something else just popped into my head.
Allergies. Have your recently used any chemicals on your floors? Carpet cleaner? Stain removers? Chemical cleaners on hardwoods? Have you sprayed or spread anything in the yard where the dog spends time? Have you switched laundry detergents?

It could also be a food issue (allergies or otherwise). What are you feeding her? Does it contain a lot of grains? Is it chicken based?

No parasites, ticks, fleas, etc. She isn't chewing excessively, just enough to notice the little bit of fur loss. I have only seen her do it twice.

She has about a dozen toys right now, I leave 2 to 3 with her in her crate each day. I don't dare put a blanket, she would destroy it. She has a blanket for her bed in our bedroom, and that's almost destroyed. She has plenty of room to lay down, stand up, turn around and even on occasion chase her tail.

She is definitely teething. She's lost at least 4 teeth, probably more. She is walked before work, at lunch and several times in the evening. At lunch we spend about 20 to 30 minutes outside.

She is on the same food I put her on right after I got her, well the same brand at least. Yes, it's grain free.

I did set up my laptop to record her during the day. I could only get 3 hours at a time, but the little snot just sleeps all day. I only saw her chewing on her leg once during the day. I guess that's a good thing. I am going to get her a few more toys this weekend and I guess just keep an eye on it right now. Like I said, it's not bad, just enough to notice. She isn't chewing down to the skin, the hair is just shorter in those few spots.

I'm not sure if that all makes sense, but Anouk is barking at me to take her outside and I'm sure my neighbors don't appreciate it this early in the morning.

Thanks!

If it's pretty light yet, I'd suggest just monitoring it.
It could be any number of relatively minor things.
If you see any dandruff, it could be a sign of dry skin that is causing irritation.
It could be growing pains in the joints.
It could be allergies or sensitive skin.
It could just be an odd personality quirk.
